Google just released the official specs for Google Glass (after releasing the API too) and the futuristic frames come with 16GB (only 12GB will be usable) Flash memory, 5 megapixel camera for stills, 720p video recording, Wi-Fi b/g, Bluetooth and a battery that can handle "one full day of typical use".

Of course with a product like Google Glass, its specs won't tell us how much we'll actually use the, um, specs. Here are the nuts and bolts of Google Glass:

Battery
One full day of typical use. Some features, like Hangouts and video recording, are more battery intensive.

Charger
Included Micro USB cable and charger.
While there are thousands of Micro USB chargers out there, Glass is designed and tested with the included charger in mind. Use it and preserve long and prosperous Glass use.
